In the embodiment illustrated, A designates a stand; B, a typewriter mounted on the stand and equipped with a. transversely movable carriage B in which is mounted a platen-roll B2; C, a strip-guide mounted on the carriage B', said strip-guide having means for supporting the form-strips as they are drawn into the typewriting machine and being equipped above the platen-roll with a rearwardly and upwardly inclined guideplate C in front of which the printed portions of the strips pass upwardly from the 100 platen-roll; D (Fig. 8), a presser device coactin with the platen-roll B2 in the intermittent eeding of the strips; E, a register device and strip-jo ging means associated with the front plate F (Figs. 1, 9 and 9), an actuating device adapted to the purpose of releasing the presser-device D and permitting the projection of the register-pins from the position shown in Fig. 8 to the position shown in Fig. 8a; G (Figs. 1 and 5-7) means for supporting and automatically feeding ink ribbons, or carbon ribbons; H (Figs. 3 and 4), a guide-member mounted on the rear upper portion of the main frame of the typewriter and equipped with cam-Studs H', either one of which studs may serve to engage the means for actuating the copy-ribbons; I, a. strip-supporting frame mounted on the stand A and projecting rearwardly therefrom, the frame I being, in the illustration given, equipped with a strip-carrying roll I'; and J, form-strips adapted to be fed through the machine and typed.

The supporting-stand A may be of any suitable construction. In the illustration given, the stand is shown provided at its rear upper portion with a cross-bar 1 and at its upper central portion with a cross-bar 2, these members serving to support the frame I.

The typewriter B may be assumed to be of standard construction, except for attachments enabling the machine to be used conveniently and effectively for filling in the forms of the form-strips and tearing off the slips which have been printed, `or filled in.

The t pewriting machine illustrated is a standard7 large size Remington machine. The main frame of the machine B is designated 3. It is equipped with transverse guides, or tracks, 3 which support rollers 4 (Figs. 1 and 5) which are engaged by transverse guide-rails 4 with which the carriage B is equipped.

The carriage is fed across the main frame in the usual manner as the typing operation proceeds. The type bars 5 (one shown in Fig. 3) are mounted on the main frame and actuated in the usual manner by means of the keys 5". The carriage is actuated by means of a clock-spring 6 (Fig. 14) which is housed in a drum and to a fixed shaft 6b mounted on the main frame. The movement of the carriage is controlled by a. rack 7 which is engaged by a. pinion 7 mounted on a shaft 7l suitably journalled on the main frame. The drum 6 is connected by means of a strap' 8 with a goose-neck member 9 fixedly mounted on the typewriter carriage. The shaft 7" is equipped with an escapementwheel 10 which is controlled in the usual way to permit the feeding of the carriage as the typing proceeds.

The main frame of the typewriting machine is ordinarily equipped with a ribbon 11 (Figs. 3 and 8) which passes at the center of the machine hack of a, forked guide 12 at a point Where the type makes the impression. In the illustration given, provision is made for feeding an original strip and three copystrips through the machine, and the mechanism G is equipped with three ribbons adapted to produce the copies, these three ribbons being designated 11a.

The carriage B' of the typewriter is equipped with the usual devices for ell'ecting the turning of the platen-roll, making various adjustments etc. Some of the fea.- tures ordinarily present for these various purposes have been omitted from the drawings, for clearness of illustration. The platen-roll is shown equipped with a knob, or wheel, 13 by means of which the platenroll may be turned to effect the feed of the strips. Other devices for controlling the angular position of the roll, etc. are omitted, for the sake of clearness.

The frame C (Figswl, 3, 8 and 13) preferably comprises a pair of sheet-metal bracketmembers having standard portions 14 mounted on and rising from the rear rail 4a of the carriage B', said bracket-members being equipped with rearwardly extending arms 14a; the inclined front plate C' which is attached to forward extensions 14h of the bracket-members; a front set of transverse guide-rods 15 .disposed a short distance back of the platen-roll; and a rear set of transverse guide-rods 16, the guide-rods mentioned being supported at their ends by the bracket-members 14 and the rearward extensions 14a thereof.

The strips of paper are supported on the guide-rods as will be clearly understood from Fig. 8. The guide-rods are equipped with adjustable edge-engaging members 17 which serve to center the strips properly in their passage through the frame C.

The presser-device D which co-acts with the platen-roll B2 is of well known construction. It comprises small rolls 18 (Fig. 8) mounted in a cradle 18Il which is adapted to embrace the lower portion of the platen-roll. The device D comprises suitably related levers which carry the cradle 18 and the rollers 18. One of these levers 19 is shown equipped with an arm 19 adapted to be actuated through the medium of a shaft 2O and a cam-arm 20 to Withdraw the presser-device from the platen-roll, it being noted that a suitable spring, or springs, such as the spring 21 normally causes the presser-device to engage the strips of paper which pass about the platen-roll. The shaft 2() is equipped with an actuating arm Q()b which, as shown in F ig. 9, is adapted to be actuated by the device F.

It may be stated that the presser-device D really constitutes a part of the feeding mechanism. That is, the device D co-acts with the platen-roll B2 to effect feeding of the strips.

The register and edge-jogging mechanism E will be understood by reference to Figs. 8-13. It comprises a rock-shaft 22 equipped with spring-projected register-pins 22a, an actuating arm 22", cam-arms 22, anda torsion-spring 22"; a rock-shaft 23 equipped with a cam-arm 23 and equipped also with bent arms 23" adapted to hold the registerpins 22 in retracted position, as shown in Fig. 8; and a pair of edge-jogging devices 24, each of said devices being secured at its upper end by a pivot-screw 25 to a slotted bracket-member 26 which is secured 'to the rear surface of the plate C. Each of the members 24 has a cam-arm 24 and a tappetarm 24", each tappet-arm being provided with a rearward extension 24"'.

The register-pins 22 are in the form of sleeves which have closed front ends of rounded formation. These sleeves are slidably mounted on pins 22 which pro'ect forwardly and upwardly from the s aft 22. The sleeves are provided with flanges 22. Between these flanges and the rock-shaft 22 are confined coil-springs 22g.

The plungers 22 are adapted to work through slots 27 in the front guide-plate,

or rest-plate, C. The arms 23" with which the rock-shaft 23 is provided are adapted to hold the register-pins 22 in retracted position normally. The arm 23 normally is held in the elevated position shown in Figs. 1 and 9 by a cam constituting a portion of the mechanism F. When the mechanism F is actuated to throw the presser-device D to the released position shown in Fig. 8, the arm 23 is permitted to drop, thus allowing the register-fingers 22 to be projected through the slot-s 27 with the paper strips released from pressure and the register-fingers 22 engaging register-perforations 28 with which the stri s are provided, the lever 22" may be actuate to oscillate the shaft 22, thus causin the register-fingers to swing upwardly am? downwardly, as will be understood from Fig. 8. In this action, the camarms 22 serve to swing the members 24 about the pivots 25, and thus the tappet-arms 24" are swun towards each other, thus tapping the opposite edges of the strips of paper and insuring proper longitudinal registration of the strips. At the same time, proper registration of the forms on the strips is secured by the register-fingers 22,

The arm, or actuating lever, 22" works through a slot 29 in the plate C; and the forward extensions of the tappet-arms 24" work through slots 30 in the plate C. The slots 30 are of sufficient length to permit adjustment of the joggers, or tappet-devices, 24.

As appears from Fig. 11, the devices 24 are equipped with springs 24x which actuate thev members in one direction, while the camarms 22 actuate them in the other direction. As shown, the rock-shafts 22 and 23 are suitably journalled in the frame C.

The device F which serves to release the presser-device D from the platen-roll and to permit the register-fingers 22 to be projected through the register-perforations 28 of the strips consists of a bell-crank 31 journaled in a bearing 32 with which the typewriter carriage B is equipped, the bell-crank 31 having a long actuating arm 31 and a shorter arm 31".

The arm 31" is equipped with a pin 33 having pivotally connected therewith rearwardly extending links 34 and 35. The link 34 is in the nature of a thrust-bar which has a reduced extension at its rear end which extends through a perforation 34 in the arm 20". The link 35 is connected at its rear end to a wrist-pin 36 carried by a crank-member 36 journalled on a pivot-stud 37 which is secured to the bracket-member 14. The member 36 is equipped with a cam 36" which serves to actuate the arm 23 as will be understood from Fig. 9. When the crank 31 is thrown rearwardly from the position shown in Fig. 9, the member 20" is actuated to release the presser-device D which cooperates with the platen-roll, and, at the same time, the flat-portion 36C of the cam 36" is brought into position to permit the arm 23 to drop, thus permitting the register-lingers 22 to he projected to the position shown in Fig. 8*.

As shown in Figs. 8 and 13, the inclined front piece, or paper-rest, C is equipped centrally at its upper edge with an upwardly and rearwardly curved finger 38.

Referring to Figs. 3, 10 and 13, 39 designates a tear-olf bar, or strip-severing device. This bar is provided at one end with an openended slot 39 and at the other end with a T-slot 39". These slots engage headed studs 40 with which the lower portion of the inclined front plate C is equipped. The upper edge of the bar is bevelled to provide a tearing edge, as indicated at 39.

The bar 39, as appears from Fig. 8, is disposed a short distance above the plane of the carbon ribbons.

The mechanism G for supporting and feeding the copy ribbons 11 will be understood by reference to Figs. 1, 3, 5-7. This device comprises a pair of horizontal plates 41 disposed at the front corner portions of the typewriter carriage and formed integrally with a crosspiece 41 equipped with a forwardly projecting flange 41b which overlies the front rail 4 of the typewriter carriage; studs, or posts, 42 rising from and secured to the lower ends of the plates 41, said studs being threaded at their upper ends and having screwed thereon nuts 42 which terminate at their upper ends in hollow-handled posts 42"; drums or spools 43 journalled on the posts 42 just above the plates 41 and resting on leather pads 43, the spools 43 having the ends of the ribbons 11a wound thereon; removable tubular clutch-members 44 disposed above the spools and equipped at their lower ends with pins 44 which engage perforations with which the upper walls of the spools are provided and equipped at their u per ends with clutch-fingers 44b which are ormed by slotting a flange with which the member 44 is provided; springs 45 interposed between the nuts 42a and a shoulder 44 at the lower end of the bore of the `member 44; and an actuator, designated generally G', which is adapted to be applied to the clutch-device 44 at either side of the machine, said actuator comprising a tubular clutch-member 46 adapted to slip freely over the nut 42" and engage the clutch-member 44, a pair of ratchet-disks 47 and 48 fitted on the reduced sleeve 46a and secured, by means of screws 49, to the member 46; a bent lever 50 having its base end journalled on a bearing 51 with which the member 46 is provided, said lever being provided with a slot l adapted` to engage either one of the cam-studs H; a. housing-member 52 forming with the baseportion of the lever a housing for the pawls employed; a double acting pawl 53 pivotally mounted on the base-portion of the lever 50 through the medium of a screw 54, said pawl having an upper pawl-arm 53a adapted to engage the upper ratchet-wheel 47, and having a lower pawl-arm 53b adapted to engage the lower ratchet-wheel 48, and said pawl being further provided with an arm 53c through the medium of which the pawl may be thrown to one position or to the other, depending upon which of the ratchet-wheels is to be engaged; and a spring 55 connecting the arm 53c with the off-set or vertical portion 50b of the lever 50.

The actuator G may be shifted from the clutch-member 44 at one side of the machine to the clutch-member at the other side of the machine when it is desired to reverse the directionof movement of the ribbons 11a.

The device H (Figs. 1, 3 and 4) is in the form of a stili' metal bar 56 which is supported on bracket-members 57 carried by the rear portion of the main frame of the typewriter, the end-portions of the bar being bent upwardly and inwardly towards each other, thus forming loops 56 through which the arms 14a of the paper-supporting frame C extend. The cam-studs H are mounted on the inner end-portions of the arms at the upper sides of the loops. When the carriage of the machine is fed transversely, the arms 14 are, of course, moved transversely.

The frame I whichsupports the source of supply for the form-strips J is shown as comprising U-shape bar 58 whose arms extend forwardly and rest upon the cross-bar 1 of the stand A, the front ends of the arms being equipped with hooks 58aA which en age the cross-bar 2; and standard-bars 59 w ich 'are rigidly secured to the arms of the U-shape member 58 a short distance in front of the web 58".

The lower ends of the standard-bars 59 depend below the member 58 and are provided with slots 59a in which is movably supported a shaft 6() of a short tension-roll 60". The upper extremities of the bars 59 are provided with slots 59b in which are supported the ends of the shaft 6l of the drum I upon which the form-strips are wound.

As shown in Fig. 2, the shaft 61 has an extension 61 which is engaged by a frictionsleeve 62 provided with an adjusting screw 62a. The arm 69b of the friction-device is equipped with a stud 62 which engages one edge of the standard 59. By means of the adjustable friction-device, the desired amount of friction may be placed on the shaft of the drum I.

In practice, it is preferred to have the formstrips drop in loops from the paper-roll. The upper loop preferably is the shortest and is engaged by the gravity acting roll a which serves to maintain the desired tension. The turning of the paper-roll to unwind the strips to the required degree is thus effected by the upper strip.

The operation of the machine may be described briefiy. The strips ma be threaded into the typewriter between t e platen-roll B2 and the co-acting presser-device, or feedelement, D, after the crank 31 of the device F has been thrown upwardl and rearwardly, in which action the mem er 20h serves to actuate the shaft 20 and release the device D from the platen-roll, as shown in Fig. 8. In this action, also, the cam-device 36b is rotated, thus permitting the arm 23 to fall and allowing the register-ngers 22a to be projected to the position shown in Fig. 8a.

The advance portions of the strips are interleaved with the carbon ribbons, and the perforations 28 at the advance ends of the strips are brought into engagement with the register-fingers 22a. This is accomplished while the tear-off bar 39 is removed. rl`he lever 22b is then oscillated to bring the forms into registration, and in this operation the edge-jogging devices 24 are actuated to bring the strips into accurate longitudinal alignment.

The tear-off bar 39 is then applied and the machine is thereafter operated in the same manner as an ordinary typewriter. As the typewriter carriage travels transversely across the main frame, the device G serves to adjust the ribbons 11a. The front ribbon 11 is adjusted in the usual manner.

As the typing proceeds, the strips are fed upwardly and rest on the inclined front plate C and the curved finger 38. After a set of forms has been typed, the slips are torn from the strips over the straight edge 39. The strips are then fed by means of the platenroll until a fresh set of perforations at the front edges of the strips are in position to be engaged by the register-fingers 22a; and, 1f necessary, the register-fingers are actuated to perfect the registration of the forms. From time to time, as may be necessary, the presserdevice D i's released andthe perfecting of the position ofthe forms with respect to each other is effected by means of the register and jogging mechanism.

The invention enables a standard typewriter to be used for typing or filling in printed forms, very much as autographic registers are used, except that the forms are filled in by typing rather than by writing.

While the feature of the device for employing a plurality of ribbons is shown and preferred, it is to be remarked that this -feature may be omitted in case strips of carbon paper are interposed between the continuous form strips before the strips are wound into the roll shown in Fig. 1.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
